M3 Brass Hex Standoff

Threaded hexagonal brass standoffs with M3 male-to-female configuration for PCB mounting and board-to-board spacing. The male stud threads directly into a mating hole while the female end accepts an M3 screw, enabling secure stacking without additional hardware.

• All dimensions in mm, tolerance +/- 0.01 mm. Additional dimensions available on request.

Benefits #

M3 brass hex standoffs eliminate the need for separate nuts and washers in PCB mounting by integrating male and female threads into a single component. In multi-board assemblies, incorrect board-to-board spacing causes connector strain, component collision, and insufficient airflow for thermal management. These standoffs provide exact, repeatable spacing that prevents these failures. The male-to-female configuration allows stacking multiple standoffs for taller assemblies without additional fasteners. Brass conductivity provides a grounding path between boards and chassis, reducing electromagnetic interference in sensitive electronics. Nickel plating ensures solderability during wave-soldering processes and protects against corrosion in humid operating environments.

Common Applications #
